The current annual GMST is about 15 °C (59 °F), [6] though monthly temperatures can vary almost 2 °C (4 °F) above or below this figure. [7] The data clearly shows a rising trend in global average surface temperatures (i.e. global warming) and this is due to emissions of greenhouse gases from human activities.
The global average covers 97-98% of Earth's surface, excluding only latitudes above +85 degrees, below -85 degrees and, in the cases of TLT and TMT, some areas with land above 1500 m altitude. The hemispheric averages are over the northern and southern hemispheres 0 to +/-85 degrees. The gridded data provide an almost global temperature map. [3]
The temperature in the years 2011-2020 was 1.09 °C higher than in 1859–1890. The temperature on land rose by 1.59 °C while over the ocean it rose by 0.88 °C. [3] In 2020 the temperature was 1.2 °C above the pre-industrial era. [4] In September 2023 the temperature was 1.75 °C above pre-industrial level and during the entire year of 2023 ...
Including April, the world's average temperature was the highest on record for a 12-month period - 1.61 degrees Celsius above the average in the 1850-1900 pre-industrial period.
Warming stripes. Not to be confused with Time temperature indicator. An early (2018) warming stripes graphic published by their originator, climatologist Ed Hawkins. [ 1 ] The progression from blue (cooler) to red (warmer) stripes portrays annual increases of global average temperature since 1850 (left side of graphic) until the date of the ...
Polar and alpine climates has every month of the year with an average temperature below 10 °C (50 °F). [8] [10] ET = Tundra climate; average temperature of warmest month between 0 °C (32 °F) and 10 °C (50 °F). [8] [10] EF = Ice cap climate; eternal winter, with all 12 months of the year with average temperatures below 0 °C (32 °F). [8] [10]
The highest temperature ever measured in Texas was 120 °F (48.9 °C), recorded on August 12, 1936 in Seymour, during the 1936 North American Heatwave, and again on June 28, 1994 in Monahans. The lowest temperature ever measured in Texas was −23 °F (−30.6 °C), recorded on February 8, 1933 in Seminole. [27] Climate data for Texas.
This is a list of countries and sovereign states by temperature. Average yearly temperature is calculated by averaging the minimum and maximum daily temperatures in the country, averaged for the years 1991 – 2020, from World Bank Group , derived from raw gridded climatologies from the Climatic Research Unit .
